Questions 17-18
Jones: Prehistoric wooden tools found in South America have been dated to 13,000 years ago. Although scientists attribute these tools to peoples whose ancestors first crossed into the Americas from Siberia to Alaska, this cannot be correct. In order to have reached a site so far south, these peoples must have been migrating southward well before 13,000 years ago. However, no such tools dating to before 13,000 years ago have been found anywhere between Alaska and South America.
Smith: Your evidence is inconclusive. Those tools were found in peat bogs, which are rare in the Americas. Wooden tools in soils other than peat bogs usually decompose within only a few years.
17. The point at issue between Jones and Smith is
(A) whether all prehistoric tools that are 13,000 years or older were made of wood
(B) whether the scientistsâ€™ attribution of tools could be correct in light of Jonesâ€™s evidence
(C) whether the dating of the wooden tools by the scientists could be correct
(D) how long ago the peoples who crossed into the American from Siberia to Alaska first did so
(E) whether Smithâ€™s evidence entails that the wooden tools have been dated correctly
18. Smith responds to Jones by
(A) citing several studies that invalidate Jonesâ€™s conclusion
(B) accusing Jones of distorting the scientistsâ€™ position
(C) disputing the accuracy of the supporting evidence cited by Jones
(D) showing that Jonesâ€™s evidence actually supports the denial of Jonesâ€™s conclusion
(E) challenging an implicit assumption in Jonesâ€™s argument

17..clear B

There is no problem with the attribution of tools. Jones is saying attribution of tools is wrong because, if the attribution is right, then the people must have migrated more than 13,000 years ago. And as there is no evidence, he suggests that the people did nt migrate more than 13,000 years, and hence the attribution of tools is wrong.

But Smith is saying that evidence is not conclusive. He explains how there can be no evidence. Hence, determining that people people did not migrate more than 13,000 years, based on lack of evidence is wrong. Smith has no comments about attribution. He never agreed or disagreed with the way Jones connected Scientists attribution to migration more than 13,000 years. So I think D is the answer.

18..Undecided between D/E.? guessed E
